Put water and yogurt in blender. Add sunflower seeds, rice, oats, 2 tbsp sugar, sea salt, and 3 tbsp olive oil. Blend on high for six minutes, but give your blender a slight rest every two minutes so as not to over-heat the motor if your blender is not a strong one.

I now let the whole mixture sit overnight. If you wish, go directly to step 3.

Just before baking add eggs and egg whites to blender. Blend on high for 3 minutes.
